Clay Bavor, VP for Google Apps

Bavor initially joined Google in 2005 on the ads team. Right now, he tackles product management and user-experience design for Google's consumer and enterprise apps, including Gmail, Drive, Docs, as well as Google's Apps for business and education.

Lockheimer has led management and engineering efforts for Android since he joined Google in 2006 — two years before the official launch of Android 1.0 and the first Android-powered device in 2008. He added Chrome OS to his engineering responsibilities in 2014.

One of his responsibilities will be making sure the two play nice together.

(When the company announced its Lollipop OS earlier this year, Business Insider interviewed Lockheimer about how Android has evolved over the years — check out what he had to say here.)

Now, though, we imagine that that philosophy has changed, as the company's more far-flung ideas are likely to become their own companies under Alphabet. Acquisitions moving forward will likely only include companies that could help improve core Google products, including Maps, Android, and YouTube, as well as the commerce or the ads business.

Jen Fitzpatrick, VP of engineering and product management for Geo and Local

Fitzpatrick was one of Google's earliest employees: She joined the company in its first-ever summer internship program in 1999. There were only four other interns at the time, and no one had even heard of "this crazy little startup" called Google.

In between, she has also led software development for products like AdWords, Google News, Product Search, corporate engineering, and the Google Search Appliance, and cofounded Google's user-experience team.

Nick Fox, VP of communications

Google wants those products to better compete "with powerhouses like Facebook and Snapchat," reports The Information's Amir Efrati, and it may even be rolling out a new messaging product soon that works more like the hugely popular app WhatsApp.

Prior to his current position, Fox led product development for Google's search-ads business.

He had already been running the operations teams across all of Google's advertising and enterprise (Google for Work) products. Before joining Google in 2005, Philipp was AOL Germany's SVP, in charge of its marketing and sales.

As Google's VP of global partnerships, Alegre helps the company develop relationships with publishers to sell ads.

He joined Google back in 2004 and headed up sales in both the Asia Pacific region and Latin America, running its worldwide mobile efforts before snagging his current position in 2012.

Lorraine Twohill, VP of marketing

Twohill runs Google's global marketing. In the company's own words that means that she tells "the evolving story of Google to the world."

That story will probably change now that Google is a stand-alone company within a much larger entity, separated from sexy, moonshot ideas like internet balloons and self-driving cars.

It came as a slight surprise that YouTube didn't spin-off from Google under the new Alphabet restructuring, but insiders have told us that it's likely because YouTube's financials aren't ready for the limelight on their own, and because they're both essentially search and ads businesses, so there's a lot of synergy and sales crossover.

Singhal's another old-school Googler — he joined the company way back in 2000, and he has since been honored with the title "Google Fellow" (meant for the most talented engineers) for his work on Google's search algorithm.

Noam Bardin, Waze

He still leads that company within Google, and we've gradually seen Maps start to mimic some of that app's features, like traffic updates.

Giannandrea has been hustling at Google for the last five years and is responsible for the "Knowledge Graph," that informational sidebar that tries to save you from having to click any links that you sometimes see on the right side of the screen when you search for something.

"You might be interested in Albert Einstein because of his work in physics, or because of his peace activism — we sometimes have to put Einstein in the same bucket as Gandhi," he told The Verge in an interview a few years back. "We're not trying to tell you what's important about Einstein — we're trying to tell you about what humanity is looking for when they search."
